EIN-verified lead
An EIN-verified lead is a lead tied to a business confirmed by its IRS Employer Identification Number — the nine-digit number the IRS assigns to registered entities. Verification proves the company is a real, registered business, not just a name on a working email or phone. It confirms the entity exists, not only that a contact is reachable.

What an EIN is
An Employer Identification Number is the tax ID the IRS assigns to a business. It is a nine-digit number written in the format XX-XXXXXXX, and it identifies a registered entity — a corporation, partnership, LLC, sole proprietorship, and so on — for federal tax purposes.
The point for lead data is simple. An EIN maps to a real business that registered with the IRS. It is not a display name someone typed into a form. When a lead is tied to an EIN, there is a registered entity behind it, not just a label.
Entity verification vs. contact verification
These are two different checks, and they are easy to confuse. Contact verification asks whether an email or phone works — is the address deliverable, is the line in service. Entity verification asks whether the business on the record actually exists as a registered company.
A record can pass one and fail the other. An email can be perfectly deliverable and still point to a business that was never registered, or to a name that does not match any real company. A syntactically valid phone number proves a number is formatted correctly, not that a real business sits behind it.
EIN verification is entity-level. It confirms the company is a registered business first. Contact details — the person, the direct line, the inbox — are a separate layer on top of that foundation, and that layer drifts as people move, which is data decay. To see the same split applied to a live product, read email verification compared with entity verification.
Why it matters when you buy leads
If you pay per lead, you are paying for real businesses, not for well-formatted junk. A list can look clean — every field populated, every email in valid form — and still be padded with entities that do not exist. Entity verification is what separates a real prospect from a plausible-looking string.
At Stalex, every lead is tied to an EIN-confirmed business, then carries a 0–100 score and an A–D grade so you can sort by score before you dial. And the model is exclusive, not shared — an exclusive lead means that the moment a record lands in your room, no competitor of yours can buy that same record. That is the opposite of shared databases, where the same contact is sold to you and to everyone you compete against.
For the longer version — how EIN-verified business leads work and why the entity check comes before anything else — see EIN-verified business leads.
The IRS assigns every registered business a nine-digit Employer Identification Number, written in the format XX-XXXXXXX.

Illustration, not live records. Once a record is in your room, a rival of yours cannot buy that same record from Stalex. It does not stop that business being reached another way.

Request early accessFrequently asked questions
Does an EIN-verified lead mean the contact person is verified too?
No. EIN verification confirms the business is a real registered entity. Whether a specific person's email or phone is current is a separate contact-level check on top of that.
What is the difference between EIN verification and email verification?
Email verification checks whether an address is deliverable. EIN verification checks whether the business itself is a registered entity. A record can have a working email and still not correspond to a real registered company.
Can I look up an EIN myself?
An EIN is the nine-digit tax ID the IRS assigns to a business, in the format XX-XXXXXXX. Businesses use it on tax filings and official documents, and it identifies the registered entity behind a lead.
Are Stalex leads EIN-verified?
Yes. Every Stalex lead is tied to a business confirmed by its EIN, then carries a 0–100 score and an A–D grade. And because the model is exclusive, once a record is in your room no competitor of yours can buy that same record.
